Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching network accommodating a plurality of subscribers and uses the switching network from among a plurality of called subscribers which a calling subscriber desires to be selected. The present invention relates to a called subscriber selection system for randomly selecting at least one called subscriber.

[0002]

2. Description of the Related Art In a conventional switching network (for example, a telephone switching network), a calling subscriber accommodated in the switching network makes a call to a called subscriber, and the switching network uses subscriber identification information of the called subscriber. A called subscriber was selected from (for example, a telephone number) and connected to the calling subscriber.

Further, in a conventional switching network which provides a representative number service, a representative subscriber group is composed of a plurality of predetermined subscribers, and an arbitrary calling subscriber is included in the representative subscriber group. To the caller, and the switching network uses the representative group identification information (for example, representative number) given to this representative subscriber group.
A representative subscriber group was selected from among the subscribers, and a target subscriber was selected from the subscribers belonging to the representative subscriber group according to the representative selection system adopted by the exchange network to connect to the calling subscriber. .

[0004]

As is apparent from the above, in the conventional switching network, the called subscriber is simply selected based on the subscriber identification information or the representative group identification information sent by the calling subscriber. Was connected to.

By the way, recently, as seen in the example of the lottery of the lottery by the individual organizer, the organizer recruits participants who wish to be drawn or selected about a certain matter,
The number of randomly selected winners from the applicants who applied for the recruitment is increasing. In this case, conventionally, solicitation has been carried out through communication media such as mail or public media such as newspapers, radios, televisions, etc., applicants apply by communication means such as mail, and the organizer receives notification of the application,
A lottery was conducted to randomly select a winner from a plurality of applicants, and the winner was notified of the result of the lottery by communication means such as mail.

[0006] At present, when the communication medium called a telephone is widely used, it is possible to notify the above-mentioned application and the winning by telephone, but the random selection operation for the lottery is an act of the organizer until it gets tired. Could not be done on the exchange network.

[0007] However, various businesses in which a specific subscriber is randomly selected by using a communication medium called a telephone are conceivable. For example, one organizer plans and the organizer desires to be selected. To collect multiple incoming subscribers in advance,
It is also conceivable that the general or specific calling subscriber may randomly select a called subscriber from the plurality of called subscribers.

It is an object of the present invention to realize the above random selection by a switching network. That is, a general or specific calling subscriber can randomly select one called subscriber from among called subscribers who have applied or participated in the above-mentioned recruitment or planning by using only the switching network. The purpose is to

In addition to the called subscriber selection system according to claim 3 shown in FIG. 2, the called subscriber 2Q itself further includes called subscriber registration means 402 for registering the called subscriber information ID and the additional information AD in the called subscriber table 101. It is a system provided.

FIG. 5 shows the principle of the present invention (claim 8). Incoming subscriber selection system 4 disclosed in claim 9.
Is a system in the case where the calling subscriber is a calling subscriber 2P 'which is predetermined to be selected, and in FIG.
The originating subscriber is shown at 2P '.

FIG. 6 is a view showing the principle of the present invention (claim 10), and particularly relates to claim 8 shown in FIG. The incoming call subscriber selection system 4 disclosed in claim 10 is claimed in claim 9.
In the case where there are a plurality of calling subscribers 2P ′ shown in FIG.
This is a system further provided with a calling subscriber information storage means (hereinafter abbreviated as "calling subscriber table") 500 in which calling subscriber information (ID ') for identifying P'is registered.

[0016]

In the called subscriber table 101, there are registered called subscriber information IDs for respectively identifying a plurality of called subscribers 2Q which are determined to be selected in advance.

When the calling subscriber 2P executes a predetermined start operation, the called subscriber selecting means 201 starts scanning each subscriber information ID registered in the called subscriber table 101, and the calling subscriber is selected. When the 2P executes a predetermined stop operation, the scanning is stopped and the called subscriber 2Q is randomly selected and connected to the calling subscriber 2P.

In the called subscriber table 102, subscriber information IDs for respectively identifying a plurality of called subscribers 2Q which are determined to be selected in advance, and additional information AD of each called subscriber 2Q with respect to the selected contents are added. To register.

The additional information changing means 300 is used by the receiving subscriber 2
Q is a means for changing the content of the additional information AD through the exchange network, by which the additional information AD registered in the called subscriber table 102 can be changed.

The receiving subscriber selecting means 202 is the calling subscriber 2
P performs a predetermined start operation to start scanning the subscriber information ID registered in the incoming subscriber table 102, and after a certain time, the calling subscriber 2P executes a predetermined stop operation. Then, the scanning is stopped, and the subscriber information ID having the additional information AD satisfying the selected contents is taken out at random, and the called subscriber 2Q corresponding to the subscriber information ID is connected to the calling subscriber 2P.

Here, the scanning that appears in the description of the called subscriber selection means 201 and 202 means that the called subscribers 2Q to be selected registered in the called subscriber table 101 or 102 are selected one by one. The above operation is repeated when the table 101 or 102 is cycled on the table 101, and the term “stop” means to stop the scanning and determine the called subscriber 2Q to be selected.

Therefore, according to the present invention (Claim 1), when the calling subscriber 2P executes a predetermined selection start operation, scanning of a plurality of called subscribers 2Q belonging to the called subscriber table 101 is started. The scanning is stopped when the calling subscriber 2P executes a predetermined stop operation, and the called subscriber 2Q can be randomly selected. According to the present invention (Claim 2), the calling subscriber 2P performs a predetermined start operation to start scanning a plurality of called subscribers 2Q belonging to the called subscriber table 102, and the calling subscriber 2P is started. The scanning stops when a predetermined stop operation is executed, and the incoming subscriber 2Q is randomly selected only to the incoming subscriber 2Q having the additional information AD satisfying the selection contents.

Thus, regardless of claims 1 and 2, according to the present invention, one called subscriber 2Q is selected from a plurality of called subscribers 2Q which are desired to be preselected by using the switching network. It is possible for the first time to randomly select.

Here, the recruitment that the organizer calls to the called subscriber 2Q and the additional information AD added by the called subscriber 2Q will be specifically described with reference to an example. Incoming subscriber 2
In order to call Q, a certain organizer plans a selection service using the called subscriber selection system 4, and a plurality of called subscribers 2Q who agree with the plan are called by the called subscriber table 1
To the general subscribers who registered to 01 or 102 and knew the plan, the calling subscriber 2 of the called subscriber selection system 4
When P is selected and one of the called subscribers 2Q is randomly selected from the plurality of called subscribers 2Q registered in the called subscriber table 101 or 102, and when the organizer himself or his / her delegate makes an outgoing call There is a case in which one of the called subscribers 2Q is randomly selected from the plurality of called subscribers 2Q registered in the called subscriber table 101 or 102.

In the former case, for example, a general subscriber who knows this project becomes an outgoing subscriber 2P in agreement with this project, and one of the registered subscribers (incoming subscriber 2Q) is randomly registered and subscribed. This is a case where a person is selected and information is exchanged by telephone (Case A). In the latter case, the organizer sends the calling subscriber 2 as in the case of TV commercials.
This is a case where at least one viewer is randomly selected from the viewers who have become P and have become the incoming subscriber 2Q to provide goods and travel (case B).

It is convenient for subscribers who often want to be selected in the above plan to be registered in the incoming subscriber table 101 or 102 in advance. In particular, in the case of the called subscriber table 102, the called subscriber 2Q reexamines the selection contents of the planning for a new project and adds the information such as his / her own convenience or desire to the additional information changing means 300.
Can be used to add to the called subscriber table 102. In both cases A and B, if the called subscriber 2
If it is determined that Q does not participate in a new project, selection refusal information for refusing to be selected as additional information AD may be added, and if it is desired to be selected, it is selected as additional information AD. It is only necessary to add selection permission information that permits the above. Further, in case A, when the terminating subscriber 2Q can select the sex, age, occupation, etc. of the originating subscriber 2P with which the conversation is made, the terminating subscriber 2Q adds the additional information AD to that effect by a predetermined code. It may be added to the called subscriber table 102 through the changing means 300. Further, in case B, when the goods to be provided and the travel destination can be selected, the called subscriber 2Q determines the desired contents as the additional information AD in advance. The code may be added to the called subscriber table 102 through the additional information changing means 300.

Embodiments of the present invention will now be described with reference to FIGS.
It will be described in accordance with 0, 11, 12, 13, and 14. The same reference numerals denote the same objects throughout the drawings.

FIGS. 7 and 8 are explanatory views of two examples of the positioning of the called subscriber selection system 4 of the present invention in the switching network 1. FIG. 7 shows the called subscriber selection system 4 of the switching network 1. This is an example 1 of the called subscriber selection system connected to the outside, and FIG. 8 is an example 2 of the called subscriber selection system connected to the inside. Each of the called subscriber selection systems 4 described herein is illustrated by taking the system of claim 10 (FIG. 6) related to claim 9 of the present invention as an example. 7 and 8, the same reference numerals as those in FIG. 6 denote the same objects as those in FIG.

The called subscriber selection system 4 shown in FIG.
It is formed by connecting the database center 44 of the same system 4 to one exchange station 11 of the exchange network 1. In FIG. 7, the database center 44 is composed of a main memory 441 that stores an operation program of the center, a file memory 442 that stores a subscriber information ID, and a processor 443 that processes operations between these main memories. There is. In the main memory 441, the called subscriber selecting unit 2 shown in FIG.
02, additional information change unit 300 and called subscriber registration unit 40
2 and the file memory 442 includes an incoming subscriber table 102 and an outgoing subscriber table 500.

The called subscriber selection system 4 shown in FIG.
This is an example in which the incoming subscriber selection system 4 is provided inside the switching network 1, and a main memory 44 equivalent to that shown in FIG.
1 and a file memory 442, a processor 444 for processing them, and a communication device such as the well-known digital switching module (DSM).
It is composed of 121 and is formed by being connected to one switching center 12 of the switching network 1.

In FIGS. 7 and 8, reference numeral 2 is a switching network 1.
, 2M denotes a calling subscriber (hereinafter referred to as a main subscriber) who participates in the service planning of the called-subscriber selection service provider and executes the called-subscriber selection, and the reference numerals 2S ₀ to 2S _n indicates a plurality of called subscribers (hereinafter referred to as sub-subscribers) 2S who desire to comply with the same selection.

An embodiment of the present invention will be described below with reference to FIG. The main subscriber 2M asks the provider of this service to use the database center 44 in order to implement the selected service, and the main subscriber 2M based on the telephone number DN _M of the main subscriber 2M and a predetermined rule. The personal identification number PW _M etc. created by is contacted to the provider of the database center 44. In response to the notification, the provider uses the processor 443.
Is used to store the telephone number DN _M and the personal identification number PW _M of the main subscriber 2M in the calling subscriber table 500 of the file memory 442 as the calling subscriber information ID ′.

On the other hand, the subscriber 2 who desires to be selected for this selected service registers his / her own telephone number DN _s and personal identification number PW _s in the database center 44 by himself as a sub-subscriber 2S. The process of registration by the called subscriber 2S will be described below with reference to FIG. 9 (called subscriber registration flowchart (at the database center)).

[0034] subscriber 2 wishing to be selected exchange 1 the called subscriber registration number, including the self of the personal identification number PW _S
1 (step 3-1). In response to this, the exchange 11 informs the database center 44 that there is a registration request for the called subscriber number (step 3-2). At the same time, the subscriber 2 informs the database center 44 of his / her telephone number DN _S through the exchange 11 (step 3).
-3). Upon receiving these communications, the Database Center 4
The called subscriber registration unit 402 of No. 4 uses the processor 443 to register the telephone number DN _S and the personal identification number PW _S in the called subscriber table 102 of the file memory 442 as the called subscriber information ID. In the called subscriber table 102, a counter number PN is added to each of the subordinate subscribers 2S,
When the number of registered sub-subscribers 2S is n + 1, the telephone numbers DN _{S0 to} DN _Sn , the personal identification numbers PW _{S0 to} PW _Sn and the count numbers PN ₀ of the sub-subscribers 2S ₀ to 2S _n are stored in the called subscriber table 102. ~ PN _n are respectively registered (step 3-4). When the registration of the called subscriber information ID in the called subscriber table 102 is completed, the processor 443 informs the exchange 11 of the completion of registration, and the exchange 11 sends an accept tan stone to the slave subscriber 2S (step 3-5). ， Tell you that registration is complete. Upon receiving the Acceptance Stone, the sub-subscriber 2S hooks up (Step 3-
6) The process of called subscriber registration is complete.

Further, the main memory 441 of the database center 44 has the additional information changing unit 300, which is used by the sub-subscriber 2S to examine the recruitment or selection contents of the main subscriber 2M, and if necessary. Change the additional information AD. The called subscriber table 102 has a count number PN _0.
~ Additional information A of each sub-subscriber 2S corresponding to PN _n
D is stored with the act code ACT. Additional information AD
As an example, as a result of examining the selection contents of the called subscriber 2S, it can be used for the information of "accept incoming call" or "reject incoming call" that rejects it.
When this is indicated by an act code ACT, it is set to a logical "1" when the incoming call is permitted and a logical "0" when the incoming call is rejected.

The modification of the additional information AD by the sub-subscriber 2S is shown in the additional information flowchart (at the time of database center) of FIG. 2S for sub-subscriber 2S intended to change
_i (where i is any of 0 to n), and the additional information AD
Taking the case of using the call acceptance or rejection as an example, the subscribing subscriber 2S _i asks the exchange 11 to accept the call acceptance number AC ₁ (for example, “# 990 #”) or not accept the call rejection number AC. ₂ (for example, “# 991 #”), additional information change number, own telephone number DN _si and personal identification number P
_Send W _si (step 4-1). The exchange 11 informs the database center 44 that there is a change in additional information from the sub-subscriber 2S _i (step 4-2). The processor 443 of the database center 44 uses the file memory 44.
The inquiry code ACT of the called subscriber table 102 of the file memory 442 is received after confirming that it is the slave subscriber 2S _i by comparing with the personal identification number PW _si of the table 102. It is checked whether it is an admissible logic "1" or an incoming call rejection logic "0", and it is changed to a logic "1" or a logic "0" depending on whether it is AC ₁ or AC ₂ (step 4-). 3). When the change is completed, the database center 44 informs the switching center 11 to that effect (step 4-4), and the switching center 11 sends an accepttan stone to the sub-subscriber 2S _i (step 4-4).
-5), and in response, the sub-subscriber 2S _i hooks on (step 4-6) and the process of changing the additional information is completed.

Next, the process of subscriber selection by the main subscriber 2M will be described with reference to FIGS. 11, 12, 13, and 14. FIG. 11 is a flowchart for selecting a called subscriber (at the time of the database center) (part 1), and FIG. 12 is a flowchart for selecting a called subscriber (at the time of the database center).
(No. 2), FIG. 13 is a counting example of the selection counter provided in the processor 443 used for random selection, FIG.
4 is an example of the called subscriber table.

A public notice means (for example, television, radio, newspaper, etc.) that the organizer who conducts the recruitment or selection service provides the subscriber 2 with the recruitment or selection service using the subscriber selection service. Will be published by
The sub-subscriber 2S examines the contents of the published recruitment or selection service and, if necessary, changes the additional information AD by the process shown in FIG.

Hereinafter, the case where the additional information AD is information for adding the availability of the incoming call will be described as an example. Main subscriber 2M
11 randomly selects one of the sub-subscribers 2S from the sub-subscribers 2S ₀ to 2S _n whose incoming call acceptance state is logical “1” according to the flowcharts of FIGS. 11 and 12, and selects the sub-subscriber selected. Notify that you have been selected for 2S. Here, FIG. 12 is a flowchart which is continuous with FIG. 11, and is divided for convenience of space.

In FIG. 11, the main subscriber 2M is the switching network 1
To the main subscriber 2M with a predetermined called subscriber selection service number AC ₃ (for example, “# 999 #” number).
The personal identification number PW _M is transmitted (step 5-1). The exchange 11 that has received the call from the main subscriber 2M analyzes the calling subscriber (step 5-2). Therefore, the exchange 11
When it is determined that the main subscriber 2M is a normal subscriber (step 5-3), the received symbols and numbers are translated (step 5-4), and as a result, the received symbols and numbers are received. If it is found that subscriber selected service number AC ₃ (step 5-5), the mobile switching center 11 is the main subscriber 2M receiving subscriber selected service number AC ₃ of the database center 44, PIN PW _M and a telephone number DN _M is transferred, and the database center 44 is requested to read service information from the main subscriber 2M (step 5-6).

Therefore, the processor 443 of the database center 44 uses the telephone number DN _M transferred from the exchange 11.
And by matching the telephone number and the personal identification number is stored a password PW _M to the calling subscriber table 500 of the file memory 442, to ensure that the main subscriber 2M is already a subscriber registered (Step 5 -7). After confirmation, the processor 443 determines that the called subscriber selection unit 2 of the main memory 441
02, and the activated called subscriber selection unit 202 instructs the processor 443 to start counting the numerical values used to select the called subscriber. Upon receipt of the instruction, the incoming subscriber selection counter provided in the processor 443 starts counting (step 5-8), and at the same time, the switching center 11 starts counting for the main subscriber 2M. It is instructed to transmit the signal sound for notifying (step 5-9). Upon receiving this instruction, the switching center 11 starts counting and starts to send a special tone to the main subscriber 2M informing that it is currently counting (step 5-10).

Here, FIG. 13 for explaining the counting state
(A), (b) and (c) of FIG. 14 and the count number stored in the called subscriber table 102 and the example of the called subscriber information shown in FIG. The operation of will be described.

As an example, FIG. 14 shows the recording capacity of a maximum of 4096 called subscribers 2S, and therefore 0000 to 4095.
Shows a called subscriber table 102 with count numbers of The called subscriber selection counter is the called subscriber selection unit 20.
According to the instruction of 2, the count is incremented from 0 to n one by one at a predetermined interval, and when n is reached, the count is returned to 0 and the count is repeated. That is, according to the above example, the incoming subscriber selection counter counts up from 0 to 4095 one by one, and when it reaches 4095, it again counts up from 0.

The above will be described in detail below. If the count of the called subscriber selection counter is 1023, for example, when the count instruction is not yet received from the called subscriber selection unit 202 ((a) in FIG. 13), the count is incremented when the count instruction is received. Of Figure 13
It starts from the first digit as indicated by the arrow in (b).

The above corresponds to the start of scanning described above. next,
The calling subscriber 2M listening to the special tone sends a stop code (SC) (for example, "#" number) to the database center 44 via the exchange 11 (step 5-1).
1) and the receiving subscriber selection unit 202 displays the stop code SC
5-12), and instructs the counter for counting the number of called subscribers, which is counting up, to stop counting, and instructs the switching center 11 to stop the special tone, and the pitcher tone is stopped (step 5-13), the counting of the called subscriber selection counter is stopped (step 5-14).

When the counting is stopped, the processor 443 reads the count value from the called subscriber selection counter (step 5-15), and the additional information AD (is added to the count number equal to the count value from the called subscriber table 102 of the file memory 442. Here, whether the incoming call is allowed or not is A
The presence or absence of CT code is checked (step 5-1).
7).

If the additional information AD is present, the ACT code indicating whether or not the incoming call is permitted is checked (step 5-18). If the incoming call rejection logic is "0", one count is added (step 5). -19) Return to step 5-15 of reading the counter value and perform the above steps 5-16, 5-17, 5-
18 and 5-19 are repeated until the logic "1" of the incoming call acceptance is reached. FIG. 13C shows a case where the count value when the called subscriber selection unit 202 receives the stop code SC and stops counting is 2047, and FIG. 14 shows that the additional information AD of the count number 2047 is received. Rejection logic "0"
Is shown. Therefore, in accordance with step 5-19, the count is incremented by 1 to become 2048, and if the additional information AD of the count number 2048 of the called subscriber table 102 is the logic "1" of call acceptance, step 5-18.
The answer is YES, and the flow leads to * 3. If the additional information is not controlled, step 5-17 becomes NO, and the flow is linked to * 3 as in the above.

The above corresponds to the above-mentioned scanning stop. next,
The flowchart shifts to FIG. 12, and as shown by the flow of * 3, the processor 443 refers to the called subscriber table 102 and the called subscriber information of the count number (2048 in the above example) selected by the called subscriber selection counter. Is read (step 5-20), and the read called subscriber information is sent to the exchange 11 as a service information read response (step 5-21). Based on the response from the processor 443, the exchange 11 performs the incoming call processing in which the telephone number included in the read incoming subscriber information is used as the incoming subscriber number.

The switching center 11 checks whether the called subscriber is a general subscriber based on the read information of the called subscriber (step 5-22). It is confirmed whether the call is a call for the above-mentioned call or a call for a called subscriber using this system (step 5-23), and if it is the latter, the called subscriber 2S is called by special ringing (steps 5-24 and 25). A call is made between the originating subscriber 2M and the terminating subscriber 2S by the normal call originating / receiving process (step 5-26) (step 5-2).
7).

In step 5-5 of FIG. 11 above, if the number received by the exchange 11 from the calling subscriber is not the called subscriber selection service number, the exchange 11 determines that the calling subscriber is the main subscriber. It judges that it is not 2M and does not connect the calling subscriber to the database center 44. In addition, in step 5-7, the calling subscriber sets the calling subscriber table 5
If it is not registered in 00, the processor 443 determines that the calling subscriber is not the main subscriber 2M, and the database center 44 does not accept it.
Notify the originating subscriber through 1. Further, in step 5-22 in FIG. 12, if the called subscriber indicated by the read called subscriber information is not a general subscriber, the process is interrupted and the fact is notified to the calling subscriber 2M.

The above description with reference to FIGS. 11 and 12 is for the embodiment of the called subscriber selection system 4 shown in FIG. 7 in which the database center 44 is provided outside the exchange. Even if the selection system 4 is provided in the exchange, the flow of the selection process is shown in FIGS.
Same as 2.

As is clear from the above description, according to the present embodiment, each sub-subscriber 2S registered in the incoming subscriber table 102 has a predetermined incoming call acceptance number AC ₁ and incoming call rejection number AC ₂ . By selecting, it becomes possible to set the incoming call acceptance state and the incoming call rejection state at any time, and the main subscriber 2M
Starts a scan of the sub-subscriber 2S which has been set to the incoming call acceptance state at the time of this call by sending a predetermined called subscriber selection service number AC _3, and sends a stop code SC at a time when it thinks it is appropriate. Stop this scan by doing
At the time of stopping, the subordinate subscriber selected at random is connected as the subordinate subscriber 2S as the receiving party.

It is to be noted that FIGS. 7 to 12 are merely examples of the present invention, and the main subscriber 2M is not limited to the one defined independently of the sub-subscriber 2S, and the called subscriber table is shown. Many other modifications can be considered, such as setting any sub-subscriber 2S registered in 102 as the main subscriber 2M. However, the effect of the present invention does not change in any case. Needless to say, the switching network 1 to which the present invention is applied is not limited to the one shown in the figure.
